Champion Men's Woven Sport Shorts
Lower concern. Standard woven shorts unlikely to have water-repellent coating treatment.
Champion woven sport shorts are basic athletic wear with no water-resistant or stain-resistant claims. No PFAS disclosure found, but untreated woven materials present lower concern than coated performance fabrics.

The full breakdown
What it's made of and why it matters
Champion's woven sport shorts are constructed from a polyester/nylon blend, both synthetic polymers that are chemically stable at body temperature and during normal washing. Woven construction (rather than knit) means the fibers are interlaced under tension, creating a fabric less prone to shedding microplastics compared to looser knits or fleeces. Untreated woven polyester/nylon does not typically require finish coatings that introduce dyes, resins, or flame retardants, keeping chemical inputs relatively low for a synthetic garment.
The brand's record and disclosure
Champion has not published detailed chemical transparency reports or restricted substance lists comparable to brands like Patagonia or PACT. The company has faced no major product safety recalls for chemical contamination in recent years. Champion does not advertise certifications like OEKO-TEX or bluesign that would signal third-party testing for heavy metals or harmful dyes, leaving chemical composition largely opaque to consumers.
How it compares in its category
Woven polyester/nylon shorts are typical mid-market performance apparel with fewer documented hazards than heavily dyed cotton blends or elastane-heavy fabrics. They occupy a safer space than flame-retardant treated athletic wear or garments using reactive azo dyes, which carry known allergen and toxicity risks. Competitors like Nike and Adidas offer similar constructions at comparable price points without stronger safety transparency.
If you buy it
Wash before wearing to reduce loose dyes or finishes. Machine wash in cool water and avoid high-heat drying, which can degrade synthetic fibers and potentially release volatile compounds. Do not bleach. Polyester/nylon blends are durable; plan to replace after 50+ wash cycles or visible pilling. Store in a dry area; synthetics absorb moisture and odor but resist mildew better than natural fibers.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Azo dyes and synthetic colorants
Polyester garments are often dyed with azo dyes, some of which can break down into carcinogenic amines under sweat, friction, or bacterial action. No specific Champion safety data is published; the risk depends entirely on dye selection and testing, which is not disclosed.
Formaldehyde resins (wrinkle finishes)
Woven polyester/nylon shorts are typically not treated with formaldehyde-releasing resins used on cotton or cotton blends. No evidence suggests Champion applies such finishes to this product type, but lack of transparency means it cannot be ruled out entirely.
Antimony in polyester
Antimony trioxide is a common catalyst in polyester manufacturing and may remain as trace residue in finished fabric. Dermal contact with low antimony levels is generally considered low-risk, but systematic testing data for Champion garments is not publicly available.
Microplastic shedding
All polyester garments shed microfibers during washing. Woven construction sheds less than knits or fleeces, but repeated laundering still releases synthetic microplastics into wastewater. This is an environmental rather than direct health hazard to the wearer.
Heavy metals in dyes and pigments
Lead, cadmium, and chromium can appear in cheaper synthetic dyes and pigments. Champion does not publish restricted substance limits or third-party dye testing reports, so the presence or absence of such metals cannot be confirmed.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
